Sanitary ware ceramics are typically made from a mixture of natural raw materials, such as clay, feldspar, Kaolin, and silica, which are processed and fired at high temperatures to create a dense, non-porous material.

The raw materials are mixed, shaped into the desired forms using techniques like casting or pressing, and then fired at high temperatures to create the finished sanitary ware products.

Generally, firing temperatures for sanitary ware ceramics can range from around 1200°C (2192°F) to 1300°C (2372°F) or even higher. 

Kiln furniture plays a significant role in the production of sanitary ware ceramics. Proper kiln furniture design and arrangement contribute to the successful production of high-quality sanitary ware products.
